摘要

Capacitive deionization (CDI) is an emerging water desalination technologyfor removing different ionic species from water, which is based on electriccharge compensation by these charged species. CDI is becoming popularbecause it is more energy-efficient and cost-effective than other technologies,such as reverse osmosis and distillation, specifically in dealing with brackishwater having low or moderate salt concentrations. Over the past decade, theCDI research field has witnessed significant advances in the used electrodematerials, cell architectures, and associated mechanisms for desalinationapplications. This review article first discusses ion storage/removal mechanismsin carbon and Faradaic materials aided by advanced in situ analysistechniques and computations. It then summarizes research progress towardelectrode materials in terms of structure, surface chemistry, and composition.More still, it discusses CDI cell architectures by highlighting their differentcell design concepts. Finally, current challenges and future research directionsare summarized to provide guidelines for future CDI research.
